SELF-REGISTERENG CHECK-PUNCH.

SPECIFICATION forming part of Letters Patent No. 642,955, dated February6, 1900.

Application filed May 23,1899.

To all 21/71/0122, it may concern.-

Be it known that I, GEORGE M. BRADT, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, haveinvented certain new and use ful Improvements inSelf-Registering Check- Punches; and I do hereby declare the follow ingto be a full,clear, and exact description of theinvention,such aswillenable others skilled in the art to which it appertains to make anduse the same.

This invention relates to an improvement in self-registering punches ofthe kind used in commissary storessuch, for instance, as those carriedon by furnace or mining companies where the employees have their wagespaid in orders on the store.

The object is to provide a simple mechanism by which the amount of eachpurchase may be punched from a card, while at the same time theregistering mechanism arranged in connection with the punching devicewill automatically record the amount punched out each time.

111 the annexed drawings, illustrating my invention, Figure l is avertical sectional view of my improved store check-punch. Fig. 2 is atop plan View of the same. Fig. 3 is a partial front elevation. Fig. 4:is an enlarged front view of the slide-plate and adjacent parts inpartial section on line a: an of Fig. 5. Fig. 5 is a sectional detailView.

Like letters of reference denote like parts in all the figures.

The present invention is an improvement upon that set forth in theLetters Patent granted to me on January19,1897, No. 575,616, as theassignee of Carl T. Painter, for a selfregistering check-punch.

A denotes the main casting or supporting bed or frame of my improvedcheck-punch, said casting being mounted upon the cardreceiving box 0,having a door 0. The front part of casting A is recessed at A and belowthis recess is a vertical passage a, which leads down into the box 0 andthrough which the punching-die operates. A card may be placed in thecasting and above opening a for the purpose of being punched. Adjacentto opening a is a guide a, secured in place by, a' screw or other meansand being of a spring character, so that it may act to hold Serial No.717,915. (No model.)

the card in place while it is being punched. The part A of the bed orframe which is directly above opening a" is formed with a vertical boreor passage to receive the verticallymovable punching-rod D, that carriesthe punch or die d, which operates upon the card and punches outtherefrom the desired numeral or numerals, the punched-out partsdropping down through the passage a into the box C. The rod D isprovided with a horizontallyprojecting lug D, under which is a spiralspring D which acts to normally lift the rod D, said spring D being heldin a recess in the upper part of that portion of the frame designated A.Said bored part A of the frame is provided above with ears or lugs A Ain which'is pivoted acam-shaped casting E, that operates from the upperend of the vertical rod D. The forward part of casting E is formed witha flat bar E, having stops ee at each end, and on this bar E is designedto rest and be capable of sliding between the stops 6 e a pivotedangular bar F, the rear end of which is pivoted by a pivotpin f to thebearing projection E on the rear side of casting E, while the front partof bar F has a horizontal forwardly-projecting pin F and above that ahandle F, whereby the cam can be operated and the handle-bar Foscillated sidewise between the stops e c.

The front part of casting A is chambered to receive a block G, whichrests on levelingscrews 9 g and is secured in place by means of thesecuring or clamping screw 0. This block is rabbeted on the upper side,and in this rabbet is arranged to reciprocate a sliding plate K, havinginclined slots 70, k, and out therein and provided with a horizontalend-projecting pin K against which acts a spiral spring located in arecess in the thickened bottom part of slide K, as shown in Figs. 4 and5, and which normally presses the pin K outward against the inner end ofthe chamber in frame A. At this same end of plate K the latter has arectangular notch K made therein to accommodate the position of pin Kand the endwise movement of the plate. Pivoted to the plate K is aratchet-bar L, the teeth of which are normally kept in engagement with atoothed wheel M by means of the flat spring Z. When the plate K isreciprocated toward the right, (see Fig. 4,) the result is to rotate thewheel M to a greater or less extent, varying according to the distancewhich the plate K moves in its reciprocation. Wheel M actuates a trainof wheels belonging to any suitable registering mechanism. Thismechanism may be of the kind shown and described in my former patent,hereinabove alluded to, or any other acceptable form, and it istherefore unnecessary to further describe the details thereof here.

On the rear side of sliding plate K is a stationary slotted plate H,that is secured to the block G by means of screws 71, and on the frontside of plate K is another slotted plate I, that is suitably held inplace. The slots 11 in plate I are directly opposite to and of similarshape to the slots in plate H. The sliding plate K moves easily betweenthe two plates H and I, and when plate K is in its extreme position atthe left the upper ends of its slots 70, 7t, and will be coincident withthe upper ends of the slots of the guide-plates H and I, as shown inFig. 3. The slots of plates H and I are slanted or inclined from the topuntil they reach a short distance from the bottom, when they becomevertical. They are variously inclined to operate the sliding plate K tothe position desired. These plates H and I are of course rigid, and twoare employed for the purpose of more evenly and accurately guiding thesliding plate K. At the front of the plate I is a shield J, which isfastened upon the horizontal ledge of the plate I by means of screws jj.

Above the plates K, I, and H are the handle F and the projecting pin Fthe latter being adapted to'be forced down into the slots of plates Hand I and also the slots of slide-plate K whenever the handle F ismanipulated for this purpose. It will be observed that the slots 7c, 70,and k vary as to their inclination. Hence when the pin F engages slot 70and pursues a vertical downward movement, guided by the slots in theplates H and I, the result will be to shift the plate K to a greaterdistance endwise than when the pin F engages the slots 70 or 70, whichare of less inclination than 70, and thus the extent of the endwisemovement of plate K will depend upon which of its slots is engaged bythe pin F The parts are so arranged and the machine is designed to be sooperated that when the pin F is engaged with the slot 70 of plate K thepunch 01 will penetrate the commissary card, severing or obliterating acertain number, which number will be indicated by the registeringmechanism, and when the pin F is engaged with slot 7;. a differentnumber will be cut or punched from the card, which number will beindicated by the register, and so a different number with respect toslot 70 Of course the plate K may have any desired number of slots andthe register be constructed accordingly with index capabilities.

Numerous changes may be made in the various mechanical parts of myinvention without departing from the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an automatic check-punch, the combination with a punching-die, ofan actuating-cam provided with a movable handle, a slotted slide-plate,slotted guide-plates therefor, said plates being engageable by a pin onthe handle, and registering mechanism actuated by the slide-plate,substantially as described.

2. In a check-punch, the combination With a spring-provided punchingdevice, of an actuating-cam, a movable handle for said cam, a slottedslide-plate, slotted guide -plates therefor,a register operated by theslideplate, and a pin on the movable handle that engages the slottedplates.

3. In a check-punch, the combination with a spring-provided punchingdevice, of an actuating-cam, a movable handle pivoted thereto and havinga f0rWardly-projecting pin, a slide-plate having diversely-inclinedslots, slotted guide-plates for the slide-plate, a register, one ofwhose ratchet-wheels is engaged by a pivotal pawl on the slide-plate,and a spring-pin in the end of said slide-plate for returning the sameto position, substantially as described.

I11 testimony whereof I affix my signature in presence of two witnesses.
